Title: Power conversion equipment
Inventor: KITAHARA NAOYUKI
IPC: H02M7/5387
Filed: 1997-08-04
Abstract: PROBLEM TO BE SOLVED: To make it possible to reduce the size and weight of a conversion equipment without increasing the power loss by forming a discharge circuit for averaging the voltage to be applied to a snubber capacitor when the switching condition of a switching element changes. SOLUTION: A snubber circuit constituted by connecting in series snubber capacitors Cs1 to Cs4 and snubber diodes Ds1 to Ds4 respectively is respectively connected in parallel to each of switching elements S1 to S4, and a snubber diode Ds1, snubber capacitors Cs2 and Cs3 and snubber diode Ds4 are respectively connected in series. Then, the snubber capacitors Cs2, Cs3 are not discharged to zero level and, in addition, by the effect of snubber diodes Ds5 and Ds8, application of a high voltage to the snubber capacitors Cs2, Cs3 can be suppressed. By doing this, the voltage applied to the snubber capacitors is averaged and thus a loss which occurs in the snubber resistors Rs2, Rs3 decreases, and then the whole of the equipment can be made smaller and lighter.

Title: Television receiver
Inventor: KAWAMURA NOBUYUKI
IPC: H04N5/44
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To obtain the optimum receiving state by seeking for the difference of a signal level between a receiving channel and an adjacent channel by means of voltage difference of RF-AGC and setting a RF-AGC operating point of the receiving channel. SOLUTION: When a channel that adjoins a receiving channel is received, a visual detection circuit 2 outputs RF-AGC voltage. In such cases, a microcomputer 4 compares the RF-AGC voltage of a receiving channel which is stored the last time with the one of an adjacent channel of this time and calculates level difference of signals. When the signal level of the adjacent channel is higher than the receiving channel, there is possibility of receiving interference from the adjacent channel. Therefore, a RF-AGC operation starting point is set a little earlier so that it may be hard to receive interference. When the signal level of the adjacent channel is lower, the RF-AGC operation starting point is set a little later to make a signal-to-noise ratio optimum.
